The operation is automatically started in advance by the warming-up time (Tw), and in the first operation, the startup time (Tp) required for the room temperature to actually reach the set room temperature (tx) after the start of operation is set. ), and in the second operation start control (on the second day) using the timer control means, the selected warm-up time (Tw) and the measured start-up time (Tp) at the time of the first operation start control are measured.
) and the new warming-up time (Tw
) (Tw - (Tw + Tp) / 2) correction is executed to automatically start operation by the new warm-up time (Tw) earlier than the artificially set time (TO), and to restart the actual operation again. The required start-up time (Tp) is actually measured, and thereafter, in each operation start control using the timer control means (each day), the warm-up time (Tw) adopted during the previous operation start control and the actual measured start-up time are used. Start automatic operation after correcting the average time (Tp) as a new warming-up time (TW), and actually measuring the start-up time (Tp) actually required in preparation for the next correction. There was one that made you repeat the same thing each time.

。However, since the correlation data provided in advance is data obtained from a general model case, the actual load conditions may differ from the model case, such as the structure and size of the actual room to be heated and cooled, differing from the model case. Due to various differences in the warm-up time (T
A large error occurs between W) and the actually required start-up time, and in each operation start control, the warming-up time (Tw) adopted last time and the previously measured start-up time (Tp) are Even if correction is performed to take the average, the above-mentioned large time error that occurred at the beginning will only be gradually reduced, but there will be a problem that will remain forever. There was still room for improvement in achieving the initial objective of achieving accurate results.

次の通りである。The characteristic configuration of the heating or cooling device according to the present invention is that after the start of operation, a predetermined warm-up time (TW ), the startup time (tx) required for the room temperature to reach the set room temperature (tx) after starting the operation is
A measuring means is provided for measuring the actual start-up time (Tp) and storing the measured start-up time (Tp), and in the next operation start control by the timer control means, the actual start-up time of the previous time stored in the measuring means is provided. The present invention is provided with a warming-up time determining means that uses the time (Tp) as the predetermined warming-up time (Tw), and its functions and effects are as follows.

ることができる。In other words, the start-up time (Tp) actually measured during operation under actual load conditions is calculated as the predetermined warm-up time (Tw).
Since the large time error that occurs at the beginning due to the load conditions being variously different from the model case will not be reduced only gradually and remain indefinitely, unlike in conventional control forms, In each of the second and subsequent operation start controls in which the time (Tp) can be adopted,
It is possible to effectively reduce the time error between the adopted warm-up time (Tw) and the actually required start-up time by appropriately considering the actual load conditions such as the structure and size of the room. .

し得るに至った。In other words, by employing the configuration of the present invention, it is possible to more accurately bring the room temperature to the set room temperature at the artificially set time than in the past, and this improves the timer function in this type of heating or cooling device. This has led to a significant improvement in reliability.

A room temperature detection means is provided to detect the room temperature a set time (Ts) earlier than O), and the detected room temperature (ts+) during the previous operation start control and the detected room temperature (ts+) during the next operation start control are provided. Depending on the deviation (Δt) from tS2),
If a configuration (configuration according to claim 2) is adopted in which correction means is provided for correcting the predetermined warm-up time (Tw) adopted by the warm-up time determining means during the next operation start control, Even if there is a difference in the load between the previous time and the next time due to differences in outside temperature conditions, the difference in load between the previous time and the next time may cause the adoption. The occurrence of a time error between the warm-up time (Tw) and the actually required start-up time can be effectively suppressed by correcting the warm-up time using the correction means, and the room temperature reaches the set room temperature at the artificially set time. This is even better in terms of being as accurate as possible.
